Re: inconsistent map behavior
To see how much heap you really need to have for your particular usage of YAAC, you can open the expert-mode Configuration dialog and enable displaying the memory utilization bar on the Preferences tab. The bar itself will appear on the map window's toolbar. you should have at least a 10% reserve. Note that specifying the -Xmx command-line option only sets the upper limit for Java heap size; if the demand is less, the actual amount of allocated heap (still more than the used heap) may be less than the maximum.

Re: APRS Group messages
For YAAC to receive from a group, you have to indicate you are a member of the group by listing it on the Message Groups table on the expert-mode Configuration dialog's General tab, and then enabling the group. This allows to leave and rejoin the group without having to delete and re-add it on the table.

next beta build#208 of YAAC, created 2025-Feb-16
next beta build #208 of YAAC ("Yet Another APRS Client"), created 2025-Feb-16
downloadable from changes and updates include: 1. set the position ambiguity correctly for raw GPS sentence position messages. 2. fix distance unit selection in preferences tab of expert-mode Configuration dialog so smaller versions of distance units for various systems of units cannot be selected by accident, and fix upgrader in case some user used the erroneous selection ability to foul up their configuration. 3. ensure YAAC and its upgraders always consistently try to find the correct path to the Java interpreter to ensure launching of upgrade stages does not fail to start the next stage. 4. fix typo introduced in build#181 that broke the calculation of Aloha circles. 5. when issuing the Locate->Station directive for a station whose position is not currently known (and YAAC sends a directed query to get the station's position), ensure that if the position report is so delayed in responding that the user is no longer viewing a map window in YAAC, the map is still updated with the received location. 6. add error check to APRS Status packet configuration to warn users if they are going to enable a status packet with text added to it, or to use Maidenhead locator position in the Status packet that report differently than the Position beacon packets also being sent. 7. fix configuration wizard to not re-create a duplicate of any GPS port in use by YAAC every time the wizard is re-run. 8. fix the packet transmission logic against incorrectly digipeating through a non-APRS port (such as the TAK plugin's port type). 9. fix symbol rendering for ATV symbol "/V" (means amateur television, not all-terrain vehicle, which is overlay code "Ak"). 10. add more entries to help index. 11. fix formatting errors in built-in help files. 12. release the timeslot usage analysis plugin, which provides extra analysis views for determining RF channel usage. 13. add support of more APRS symbols in translating APRS packets to CoT event messages. 14. fix the saving of team "color" selection in the TAK plugin. |

Re: Weather beacon position over RF
#weather
Of course, this only works if you have a working Internet connection and the same for the Internet site you are sending your data to (the APRS-IS is highly redundant if you choose to use one of the regional rotate names rather than a single hard-coded server address; I can't speak for other weather-data-consuming services).
My local ARES/RACES group has weather stations all over our county using RF to deliver the data to an I-gate physically located at the county Department of Emergency Services office, so they can get the data even if there are Internet outages (peeling it off before the I-gate sends it to the APRS-IS).

Re: Weather beacon position over RF
#weather
There are a few things you have to do to have your weather data beaconed with your position reports.
1. You have to have a weather input port opened on YAAC that is receiving the weather data. Serial_Weather accepts serial port data from Peet Bros brand weather stations; WXNOW.TXT accepts weather from any weather station being handled by Cumulus or similar weather client software. In either case, use the View->Weather Status menu choice to confirm you are actually seeing current data from your local weather sensors in YAAC. 2. In your beacon definition, you have to enable your beacon and check the box to have it Report Weather. 3. Due to a quirk in the APRS Protocol Specification, the course and speed fields of a position report always mean the course and speed of the radio station, not the wind, unless the APRS symbol code is for a weather station (/_ or \_). YAAC is smart enough to recognize when you are using a non-weather-station symbol code that would cause your wind information to be lost, and will send the Position Report (without weather information) immediately followed by a Positionless Weather Report (which doesn't care what your symbol code is). This has the convenience that you could have a mobile weather station (e.g., stormchaser) reporting the course and speed of your chase vehicle in the Position Report, plus the weather data separately. YAAC, unfortunately, does not have support for the vector math necessary to convert air velocity around a moving vehicle into ground-relative wind velocity, so your weather sensors would have to do the math prior to delivering the data to YAAC. Hope this helps.

Re: severe weather zones
Here's a few details on seeing severe weather zones:
1. You will only get severe weather alerts (forecasts) if you have an APRS-IS connection with a geographical radius (r/ or m/) or area (a/) filter large enough to include the relevant areas. These messages have position information in them to affect the filtering by the APRS-IS server, and come from a single Internet server that pushes the data from the National Weather Service onto APRS-IS. 2. The shapefiles for the 3 categories of severe weather zones need to be copied into your configured YAAC map tile directory. Just downloading them isn't enough if you don't unpack the .zip files into the correct directory. 3. You have to have Severe Weather Zones enabled on the View->Layers submenu. Note this won't prevent the zones from appearing in the Severe Weather table. 4. There actually have to _be_ severe weather events for the notifications to go out. Note that it is possible to see other weather data that looks like severe weather alerts, but isn't. These are APRS Objects describing actual weather (such as thunderstorms, tornadoes, flooding, etc.), not forecasts, which also come from the APRS-IS, and commonly have NWS multilines attached to the Objects to draw polygons around the affected area. Rendering of the multilines is controlled by a different menu choice, View->Layers->NWS Multilines. These Objects do _not_ appear in the Severe Weather table, but will appear in the Stations/Objects List. Hope this helps.
